People's Online Panel New Zealand
We are establishing NZ online panels that are samples of individuals on whom different online surveys are conducted over time.

Online panels are samples of individuals on whom different online surveys are conducted over time. Currently all online panels in New Zealand are commercially run, and are ‘non-probabilistic’ (opt-in) panels, populated by individuals who volunteer their services. The statistical validity of findings from non-probabilistic panels has been questioned.
‘Probabilistic’ online panels overcome these statistical shortcomings by randomly sampling from the population of interest. Probabilistic panels have been shown to produce robust and reliable findings that can be generalised to the greater population.
We have been awarded a University of Auckland Vice Chancellor’s strategic development fund (VCSDF) grant to establish a probabilistic online panel: People’s Online Panel New Zealand (POPNZ). POPNZ will enable researchers across different disciplines and organisations to answer key research questions without incurring the time and effort to recruit a sample.
We are currently establishing the panel. Key components of POPNZ will include:
- A stratified random sample of 3,000–4,000 sampled from 18–74 year olds from the electoral roll. Stratification is by age, ethnicity and gender.
- Offline as well as online panel members to ensure representation of those without an internet connection and of the net-averse.
- An initial frequency of 8 surveys per year, with at least four on the full sample, and up to four on a sample subgroup (e.g. by age, gender, ethnicity, Auckland region).
- Surveys on public good research topics (i.e. not for commercial gain) on health, social, public opinion, and political topics.
- Privacy and confidentiality for panel members, and ethics approval for all surveys.
- Single topic surveys as well as ‘omnibus’ surveys (several researchers contribute questions to the same survey), and capacity for longitudinal surveys.
- Surveys of 15–20 minute duration.
